The present work was carried out in newly reclaimed land at the Experimental Station of the Faculty of Agriculture (Kalabshow and Zayan), Mansoura University, Dakahlia Governorate, Egypt. to study the effect of fulvic acid, some micro elements and microorganisms on yield and its components, fruits content of macro-and microelement of Zaghloul date palm. The obtained results indicated that fulvic acid applied at 83.33 ml / palm tree + microorganisms at 83.33 ml / palm conjugation with micro elements at (3.12 gm from FeSo4.7H2o + 1.56 gm from ZnSo4.7H2o + 1.56 gm from MnSo4.H2o) as soil application / palm (T7) gave significant increase yield/ palm (174.16 and 169.33 kg), fruit weight (33.29 and 32.45 gm) and flesh weight (30.927 and 30.070 gm), whereas the yield of T1 control (96.16 and 92.23 kg/palm), fruit weight (20.34 and 19.63 gm) and flesh weight (18.47 and 17.95 gm) in both seasons of the study, respectively. All treatments of organic compounds extracts and microelements gave significant increase in the values of NPK and Fe, Zn and Mn in Date palm fruits as compared to control treatment in both seasons of the study .

Myzus persicae (Sulzer) is one of major insect pests which infest many vegetable crops especially potato plants. Some natural materials such as, neem oil, menthol oil and nano chitosan were used in controlling M. persicae. The results showed that, neem oil was the most effective compound in controlling M. persicae with LC 50 63.60 ppm, followed by menthol oil then nano chitosan with LC 50 100.26 and 101.62 ppm, respectively.

Two experiments were carried out during the two successive seasons 2006/2007&2007/2008 at El-Santa district ,Gharbia Governorate to evaluate the efficiency of five materials (Actellic,Caple (2), Garlic oil, Mint oil, and Castor oil) against Thrips tabaci It was obvious that the toxicity of Actellic, Caple (2) and Garlic oil were closely subsequent population reduction of 88.8%,82.4% and 75.8% were superior respectively.Mint oil and Castor oil showed a moderate toxicity to the population of T. tabaci they caused 67.4% and 58.7% population reduction respectively.These results concluded that successful control of T. Tabaci can be achieved by using Actellic,Caple(2)and Garlic oil at the rates of 2.5cm3/L.water ,10cm3/L.water and0.2cm3/L.water respectively.
